Data Flow in NEES

NEES Data Goals Aligned with NSF Data Management Plan (DMP) requirements*  All research data and documentation will be archived Types of data and other materials to be produced during project  Archived data will be of high quality Standards to be used for data and metadata format and content  Archived data will be accessible and shareable Policies for access and sharing  Archived data will be re-usable Policies and provisions for re-use  Archived data will be preserved Plans for archiving and preservation of access to them *

Data Archiving  Who  research team, site personnel, curator, NEEScomm  What  sensor measurements, sensor calibrations, observations, analyses, numerical simulations, images and videos, reports (including publications and presentations), logs  When  Dates are stated in the Data Sharing and Archiving Policies (1 month, 6 moths, 12 months)  For as long as the data are useful ~ indefinitely ~ for 20 years  Where  Project Warehouse  Why  increases researcher’s impact  saves work, time, money  good practice  advances science

Information Package Information Package – discoverable through descriptive information  Content Information - the original target of preservation - consists of  Content Data Object (bits)  Representation Information – needed to make object understandable to the community (record)  Preservation Description Information - information needed to preserve the Content Information  Provenance  Context  Reference (Identification)  Fixity – protect the CI from undocumented alteration  Access rights

Quality Assurance Data need to be understandable  Standards Seeing standards  Research teams  Professional standards  Team guidelines for data management  NEEScomm requirements  NEES Sites  Certifications  Professional standards  Local guidelines (naming conventions, etc.)  NEES Data Repository  OAIS  PREMIS  Dublin Core  Documentation and metadata requirements  Curation  interactive and iterative exchange  assessment of technical quality of data and relevant documentation

Access and Sharing  Time  Unprocessed data – within 1 month  Corrected data and documentation – within 6 months  Data made PUBLIC within 12 months  Conditions for access and sharing ( Let others know that they can use your data)  Open Data data  Creative Commons presentations, reports, pre-prints/post-prints, teaching materials  Open Source software more on intellectual property considerations

Data Re-Use Use of known, tested, and open formats is key to the success of any future attempt to use data  Data Use - Using research data for the current research purpose/activity to infer new knowledge about the research subject.  Data Re-use - Using research data for a research purpose/activity other than that for which it was intended.  Data Purposing - Making research data available and fit for the current research activity.  Data Re-purposing - Making existing research data available and fit for a future known research activity.  Supporting Data Re-use - Managing existing research data such that it will be available for a future unknown research activity.

Preservation  Bit-level preservation All files will be stored and preserved on the bit-level  Full preservation Required and recommended (supported) formats Preservation strategies:  format migration  format refresh  emulation
